Description and Introduction

4 M SRAM (512-kword x 8-bit) The HM62V8512BLFP-7 is a 512K x 8-bit (4M-bit) high-speed CMOS static RAM (SRAM) manufactured by Hitachi (now Renesas Electronics).  

### Key Specifications:  
- **Organization**: 512K words × 8 bits  
- **Technology**: High-speed CMOS  
- **Operating Voltage**: 3.3V (±0.3V)  
- **Access Time**: 7 ns (max)  
- **Operating Current**: 70 mA (typical)  
- **Standby Current**: 5 mA (typical)  
- **Package**: 32-pin PLCC (Plastic Leaded Chip Carrier)  
- **Operating Temperature Range**: 0°C to +70°C  
- **I/O Interface**: 3.3V TTL-compatible  
- **Features**:  
  - Single 3.3V power supply  
  - Fully static operation (no clock or refresh required)  
  - Three-state outputs  
  - Byte-wide data bus  

This SRAM is designed for high-performance applications requiring fast access times and low power consumption.

Application Scenarios & Design Considerations

4 M SRAM (512-kword x 8-bit)

Alternative Part Number

  • IS62WV5128BLL-55TLI --: 512K x 8 low-power SRAM with similar 5V-tolerant interface and access time, widely used as a drop-in replacement for Hitachi 512Kx8 SRAMs.
  • CY62128EV30LL-45ZXI --: 1Mbit (128K x 8) low-power SRAM in TSOP package with comparable speed grade and pinout, suitable functional substitute.
  • AS6C1008-55TIN --: 1Mbit low-power CMOS SRAM designed as a legacy-compatible replacement for Hitachi SRAM families, similar timing and package.
  • IS61WV5128BLL-10TLI --: 512K x 8 asynchronous SRAM with similar speed grade and pinout, widely available and often used to replace Hitachi SRAMs.
  • CY7C1041DV33-10ZSXI --: 512K x 8 low-power SRAM with comparable access time and 3.3V operation, suitable drop-in alternative.
  • AS6C4008-55PCN --: 512K x 8 SRAM in the same density class, commonly cross-referenced for legacy Hitachi SRAM parts.
